Compressalges nipponiae

Compressalges nipponiae

A parasitic mite endemic to only the Japanese Crested Ibis. The species feeds the ibis' feathers, not sucks its blood.
This mite is listed as EW by Japanese Red List, but it is believed that it is still living because a few individuals of Japanese Crested Ibis is still living in China and Japan.

A report of infection in the crested ibis Nipponia nippon with feather mites in current Japan

In this study, two feather mite species, C. nipponiae and F. nipponiae, were found on feathers of Japanese crested ibises. Within the sample of Chinese crested ibises introduced to Sado Island, all 17,800 individuals of feather mites were identified as F. nipponiae, while C. nipponiae was not observed to infect the introduced host individuals. Therefore, we conclude that C. nipponiae is truly extinct from Japan after its Japanese native host population disappeared, despite the wild population having been re-constructed by the introduction of crested ibises from China. Currently, C. nipponiae is listed as “DD” in the Red List in Japan due to the presence of the host population in Sado Island; however, based on the results of this study, we recommend a revision of the status of C. nipponiae to “EX” in near future.

Abstract

The objective of this paper is to redescribe two feather mites, Compressalges nipponiae Dubinin, 1950 (Caudiferidae) and Freyanopterolichus nipponiae Dubinin, 1953 (Kramerellidae), based on samples collected from the last two individuals of the Crested Ibis Nipponia nippon (Temminck, 1835) from the native Japanese populations, which had been extirpated in 2003. Our study provides detailed description of the leg and idiosomal chaetotaxy, and many morphological structures, which were missed or misinterpreted in the original publications.
